After back-to-back weekend storms brought visions of flooding to much of Northern California, the rain clouds parted yesterday to reveal occasional sunshine and cool nonchalance among residents and official water-watchers.

Even though the rains put Northern California over 100 percent of average seasonal rainfall, many people said their nervous monitoring of the Russian and Napa rivers and the low-key sandbagging was nothing to worry about.

"I can watch (the Russian) from my kitchen window -- no surprises," said Patrick Mahoney, who lives at the top of a shallow rise in Guerneville, a couple hundred feet from the river's proper channel. "We were ready, we had our plan: We had our sawhorses and our plywood and we knew what we were going to stack up."

Last year at this time, the river had broken out of its banks and climbed 13 feet above flood stage. At its highest yesterday, the river mustered a reading of only one foot above flood stage at Hacienda and Guerneville.

"There was a little bit of drainage backup and minor flooding at Yountville Road and Lodi Lane," said Captain Gar Harry, a spokesman for the Napa County sheriff's office. "But that was it. Nothing major."

The National Weather Service said rainfall totals for this series of storms reached 8.7 inches in Cazadero near the Russian River, 6.6 inches in Ross and 4.95 inches in Ben Lomond in the Santa Cruz Mountains.

In the most dramatic weather- related incident in Oakland, a 60- foot-tall eucalyptus tree fell onto a house in the Montclair neighborhood. The trunk remained intact but the house was cut in half. No one was injured.

The Sonoma County sheriff's office said several roads were flooded after the weekend, but only Geyser Road in Cloverdale was closed.

In the Bay Area, no rainfall was reported after 7 a.m. yesterday. Meteorologists predicted partly cloudy skies with temperatures slightly above normal for today and Wednesday.
